TROLLEY.

SPECIFICATION forming part of Letters Patent No. 765,516, dated July 19, 1904.

Application filed January 27,1904. Serial No. 190,880. (No model.)

To a/ZZ whom, t may concern:

Be it known that I, I/ViLsoN SnLAKosKY, a citizen of theUnited States, residing at Lehighton, Carbon county, State of Pennsylvania, have invented certain new and useful Improvements in Trolleys; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain improvements in trolleys, and more particularly to improvements in trolley-heads.

An object of the invention is to provid certain improvements in trolleys whereby danger of the trolley-wheel jumping or accidentally leaving the wire at curves or elsewhere will be reduced to a minimum, yet without to a disadvantageous extent increasing the weight of the trolley-head or rendering the same liable to inj'uriously engage crossings, hangers, or guy-wires.

A further object of the Yinvention is to provide a trolley-head wherein the wire-retaining groove permanently open at the top is formed by a trolley-wheel and two opposite angularly-arranged disks, said disks being arranged with the highest portions thereof at the upper portion of said groove, so that the trolley-head can pass the guy-wires, hangers, and crossings of the trolley-wire without injury thereto and without throwing' the trolley from the wire and yet so that said disks will hold the trolley to the wire at curves and at other points where the trolley-wheel without the disks might leave the wire.

A further object of the invention is to provide a simple, economical, and effective trolley-head for accomplishing the purposes intended and wherein two inclined disks are arranged on opposite sides of the trolley-wheel to form therewith the open-top wire-retaining groove and to provide the trolley-head with a finder normally withdrawn from operative position.

The invention consists in certain novel features of construction and in combinations of parts, as more fully and particularly described and set forth hereinafter.

retaining groove and the finder being shown in elevated position. Fig. t isa cross-sectional view of a modified construction.

In the drawings I show a trolley'head or frame provided with two longitudinal separated side walls, plates, or bars a, merging together at their front ends in the upper end of the trolleypole or in and'rigid with the rear end of the socket or sleeve 5 or other means of attachment to the trolley-pole. The rear ends of the frame sides a are rigidly connected by the cross-piece o, and the parallel separated rigid ears CZ project rearwardly from the rear end of said frame.

The vertically-rotating trolley-wheel e is arranged within said longitudinal opening or slot of the trolley-head frame. This wheel can be of any suitable or ordinary trolleywheel construction, preferably having the deeply-grooved flaring rim or periphery f, although, if desired, the rim need not be so deeply grooved or Banged as usually employed in the ordinary single-wheel trolley. This trolley-wheel can be revolubly mounted by any suitable means and in any suitable manner, although l have shown the same formed with the elongated hub g at its ends abutting the inner faces vof the frame sides and rotating on a transverse horizontal shaft L, passing through the hub and through ears vl, rigid with and depending from the frame sides. This shaft fz is usually endwise removable and provided with means to lock the same in the frame. 7' represents two similar disks arranged at opposite sides of the trolleywheel and frame and freely revoluble on fixed axes. These disks are angularly arranged, so that their upper portions overlap the top portion of the trolley-wheel and so that the highest portions of the disks are located immediately or approximately over the top of the trolley-wheel.

The axes of the disks are preferably arranged in the same vertical plane which includes the axis of the trolley-wheel, and the said disks are suitably mounted on or to the said frame. For instance,I show the disks turning' on studs or shafts 71;, projecting outwardly and upwardly from the opposite side frames. opposite frame sides above the trolley-wheel s hafts are shown deflected or inclined inwardly and upwardly at Z at about an angle of forty-ve degrees to each other to form bearing or supporting faces for said disks,` and the studs are shown removably screwed into the frame sides at said faces and extend-4 ing outwardly about at an angle of forty-five degrees. However, I do not wish to limit my invention to this arrangement for mounting the disks, although I prefer to removably mount the disks to permit removal of either or both, if desired, for repairs or other purposes or to permit removal of the trolleywheel for any purpose.

I prefer to make the disks as flat and light in weight as the requirements of wear and durability will permit. The disks shown, excepting' Fig. 4, are arranged at about an angle of forty-five degrees with respect to each oth er,and the upper or highest portions thereof project above the plane of the top of the trolley-wheel and at opposite sides thereof; but the topl edges of the disks do not meet. The deep trolley-wire retaining-groove is formed by the periphery of the trolley-wheel and the adjacent faces m of the two disks above the trolley-wheel. The top edges of the two opposite disks are sufficiently separated to form or leave the necessary top opening of the wire-retaining groove to permit the necessary entrance of the Wire into the groove and removal of the trolley from the wire, yet the freely and independently revoluble disks are so arranged with respect to the trolley-wheel that it is next to impossible for the trolley to accidentally jump or leave the wire at curves or elsewhere even when the car is running at a high rate of speed.

It is essential that the trolley be so formed as to freely pass the trolley-wire hangers, guys, and crossings or other obstructions, sometimes located quite close to the wire because of the general use of the small single-wheel trolley. I have hence so arranged my disks that they converge upwardly with their upper portions arranged close to the trolley-wheel, with only such parts projecting above the trolley-wheel as are absolutely necessary to form the side walls of the wire-retaining groove. In other words, the highest portions of the disks form the side walls of the wire-retaining groove and are located at the top edges of the side walls of such groove and but a comparatively slight distance apart, so as to pass all obstructions as freely for all practical purposes as the ordinary single-wheel trolley.

The,

The outer annular or peripheral portion or 'side face on of each disk is usually curved or concaved to form the annular usually-concaved wall of the wire-retaining groove in virtual upward and inward continuation of the groove-walls of the trolley-wheel, and where the fiat comparatively thin disk is employed it can be formed at its inner face with the annular rib n, arranged beside the outer side edge of the trolley-wheel.

rIhe wire guide or finder is carried by the rear ears CZ and comprises a transverse rockshaft 0, extending between and turning in said ears and rigid with the radially-extending fork formed by the elongated rods or arms p, liaring or diverging at their outer ends. The fork joins .the shaft between said ears, and one end ofthe shaft is extended through an ear and at its outer end provided with a crankarm q, to which a rope or pull connection r is attached and which depends to a point wherel it can be conveniently reached by the operator on the car. A suitable springis provided which yieldingly and normally holds the finder swung down' and rearwardly away from the trolley-wire and against the stop-rod s, fixed in the ears. This spring can be arranged in any suitable manner, although I have shown the spring' zcoiled on the extended end of the finder-shaft and suitably secured to yieldingly hold the shaft with the fork swung rearwardly. When it is desired to replace or set the trolley-head on or against the wire, the operator pulls down on the connection fr, and thereby swings the fork to vertical position against the tension of spring t, and the fork can thus readily straddle the trolley-wire and guide the same into the wire-retaining groove formed by the trolley-wheel and two disks. When the connection v' is released, the spring swings the fork down away from the wire and to inoperative position.

In Fig. L I show a modified arrangement, wherein the trolley-head or frame is provided with rigid side straps or brackets 9, forming inclined bearing-faces for the inclined retaining disks or wheels l0, arranged on opposite sides of the trolley-wheel 5, located between the sides of the trolley head or frame and turning on a suitable shaft or spindle. The disks 10 in this construction are arranged about at an angle of ninety degrees to each IOO ILO

other and turn on studs ll, and the retaininggroove walls or faces 12 of said disks are formed by the single ange rim or periphery wish to limit myself to the exact constructions shown.
